Tips to Reduce Energy

Here are the top 10 ways to reduce your energy bill in 2025 – while keeping your home comfortable all year long.

1. Use Natural Sunlight to Your Advantage

In the colder months, open shades and curtains during the day to let in Wisconsin’s natural sunshine, which can help passively heat your home. As the sun goes down, close them to trap the warmth and block out chilly drafts.

During summer, reverse the strategy: keep shades and curtains closed during peak daylight hours to keep the indoor temperature cool without overworking your air conditioner.

2. Bundle Up and Lower the Thermostat

Grab a hoodie or cozy blanket and embrace some layers indoors during winter. Keep your thermostat set to 68°F while home and awake—this simple adjustment can significantly cut energy costs.

By dressing warmly indoors, you’ll stay comfortable without having to crank up the heat.

3. Adjust the Thermostat When You’re Away

According to the U.S. Department of Energy, dialing down your thermostat 7–10 degrees for at least 8 hours a day (like when you’re at work or asleep) can reduce your annual heating bill by up to 10%.

In summer, raise the thermostat a few degrees when you’re not home. This prevents your HVAC system from running unnecessarily and reduces wear and tear.

4. Change Your HVAC Air Filter Regularly

A dirty air filter reduces your system’s efficiency and worsens indoor air quality. Change your HVAC filter according to the manufacturer’s guidelines, usually at least every 3 months or more often if you have pets or allergies.

This small step ensures optimal airflow, prevents your system from overworking, and helps lower monthly utility costs.

5. Add a Gas Fireplace for Efficient Room Heating

Do you have a large living room or open floor plan? Instead of overworking your furnace, consider installing a modern, energy-efficient gas fireplace. Today’s models are sleek, stylish, and cost-effective—and they’re perfect for heating frequently used spaces without impacting your whole-home system.

6. Replace Outdated HVAC Equipment

If your furnace or air conditioner is more than 10 to 15 years old, it may be time to plan for a replacement. Modern HVAC systems are far more energy-efficient and reliable.

This is also the ideal time to install a programmable or smart thermostat, allowing you to customize your comfort levels and reduce energy use with automated settings.

7. Schedule Annual HVAC Maintenance

Routine HVAC checkups are crucial to keeping your system running efficiently and extending its life span. Schedule a professional inspection and tune-up at least once a year.

Preventative maintenance helps you avoid breakdowns, improves system performance, and saves you money on future repairs and energy bills.

8. Seal and Insulate Your Home

Energy efficiency starts with proper insulation. Seal air leaks around windows and doors, and insulate attics and crawl spaces to prevent warm (or cool) air from escaping.

A properly sealed and insulated home means your HVAC system works less, saving you money while keeping your home more comfortable.

9. Reduce Water Heating Costs

Lower your water heater temperature to 120°F, install low-flow showerheads, and shorten your shower by just a couple of minutes.

Water heating is often the second-largest energy expense in homes. Small changes in your water usage habits can lead to noticeable savings.

10. Switch to LED Lighting

Replace incandescent or CFL bulbs with energy-efficient LED bulbs. LEDs last significantly longer, use less energy, and are more durable than traditional lighting options.

This is one of the simplest upgrades you can make—and it pays off over time.
